Of all the dinosaur movies, how this one manage to fly pass my radar is beyond me. If you love the Land Before Time, you should check this one out. It's easy to find on YouTube. 

It's about a Tyrannosaurus Rex named Heart who's having a bit of an identity crisis, as he was raised by a family of maiasaura. After learning the harsh truth of what he really, is he runs away. Years later, now an adult and full blown meat eater; he comes across an egg that hatches out a baby ankylosaurus. Ready to eat him Heart refers to the baby as "Umasou" (with means Yummy) only for the ankylosaurus to think Heart the T Rex is his dad. 

I won't go into too many spoilers at the moment but definitely check this film out if you have the time. The simple art style may take some getting use to, but one of the things I love about that is how it contrasts with the violence. Oh, yes. Unlike Land Before Time you actually get to see the carnivores eat the animal they hunt. It was quite the surprise.

Speaking of style for this I just went with how I've normally been drawing dinosaurs lately. This there is a piece in the works in the original style. So yeah...
